Need help convincing the hubs!

We are due in October and I am trying to find the perfect girls name for us. My husband is obsessed with the name Sophia. While I like the name Sophia, I am a little put off by the popularity, although none of my choices are unique either! The middle name will be my grandmothers, Antonietta. That is a mouth full but my preferences are for feminine first names. Our last name is two syllables, begins with an F and ends in er. Any help would be greatly appreciated!
